TOKYO, Aug 29 (Reuters) - Japan’s Nikkei share average rose on Thursday, snapping a three-day losing streak led by gains in oil shares, while fears abated that U.S.-led forces would soon launch a military strike on the Syrian government.

The mining subsector, which include oil refinery operators, jumped 4.9 percent and was the best sectoral performer after Brent crude prices climbed to a six-month high on Wednesday on fears of supply disruptions in the event of an escalation in the Syrian crisis. Brent crude pulled back 0.7 percent to below $116 a barrel on Thursday.
